Heterodoxy refers to beliefs or opinions that deviate from established or orthodox doctrines, particularly in religious or philosophical contexts. It encompasses a wide range of perspectives that challenge mainstream views, allowing for a diversity of thought and interpretation within various traditions. In many cases, heterodox ideas can lead to significant debates and discussions, fostering intellectual growth and innovation. Figures such as Martin Luther and Galileo Galilei are often associated with heterodox views that challenged the status quo, ultimately contributing to the evolution of their respective fields.
